An optical fiber connector

Abstract

An optical fiber connector allowing more precise connection, having a front casing and an insertion core assembly; the front casing has an installation hole where the insertion core assembly is installed: the insertion core assembly has an insertion core and a tail rod; the tail rod has a tail rod head portion and a tail rod necking portion: the tail rod head portion fixedly sleeves one end of the insertion core; the tail rod head portion has a quadrilateral cross section; a cross section of the installation hole also has a quadrilateral shape that matches the quadrilateral cross section of the tail rod head portion.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to the technical field of optical fiber connector, and more specifically relates to high precision optical fiber connector.[0002]In the prior arts, an insertion core in an optical fiber connector is movable along an axial direction of the optical fiber connector, and may rotate by a certain degree when it is compressed axially. However, these characteristics greatly affect the experimental data of the tests on the optical fiber connector. When testing the optical fiber connector, test results may deviate if the insertion core can rotate by a certain degree, and this greatly affects the test data obtained, therefore it is difficult to meet the requirement for repeatability of the test. Hence, minimizing a degree of rotation of the insertion core of the optical fiber connector when the insertion core is compressed is now an urgent issue that requires a solution. Further, after the optical fiber connector is inserted to an ...

AI Technical Summary

Benefits of technology

This patent describes an improved optical fiber connector that is more precise and accurate. It achieves this by minimizing the rotation of the insertion core when the connector is retracted, which helps to increase the stability of the connection and reduce the impact of external forces. The modification involves a change in the tail rod head portion from a hexagonal shape to a quadrilateral shape, which reduces the degree of rotation and increases the repeatability of the connection. Additionally, the curved surface of the part of the tail rod head portion connecting the insertion core and the curved hole provided in the installation hole of the front casing matching the curved surface provide guiding effect when the insertion core rebounds after compression, thus ensuring that the insertion core rebounds along the same position, thereby minimizing the rotational shift of the insertion core after rebound and therefore reducing the impact of external force on the quality of connection and hence increasing the stability of the optical fiber connector and the precision of connection. Furthermore, the present invention also modifies the rear casing, which shortens the overall length of the optical fiber connector without affecting its performance, making it more securely fixed to its corresponding adaptor.

Problems solved by technology

However, these characteristics greatly affect the experimental data of the tests on the optical fiber connector.

When testing the optical fiber connector, test results may deviate if the insertion core can rotate by a certain degree, and this greatly affects the test data obtained, therefore it is difficult to meet the requirement for repeatability of the test.

Hence, minimizing a degree of rotation of the insertion core of the optical fiber connector when the insertion core is compressed is now an urgent issue that requires a solution.

Further, after the optical fiber connector is inserted to an adaptor, external force possibly exists at a back side of the optical fiber connector may affect the connection of the optical fiber connector with the adaptor, and minimizing such impact to the connection is also an urgent issue that requires a solution.
